Cylinder Heads

Installation (cont'd)

6. Install the head cover gasket in the groove of the

cylinder head cover. Seat the recesses for the cam-

shaft first, then work it into the groove around the

outside edges.

NOTE:

Before installing the cylinder head cover gasket,

thoroughly clean the seal and the groove.

When installing, make sure the head cover gasket

is seated securely in the corners of the recesses

with no gap.

HEAD COVER

Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

Use liquid gasket, Part No. 08718 - 0001 or 08718

-003.

Check that the mating surfaces are clean and dry

before applying liquid gasket.

Do not install the parts if five minutes or more have

elapsed since applying liquid gasket. Instead, reap-

ply liquid gasket after removing old residue.

After assembly, wait at least 30 minutes before

filling the engine with oil.

Apply liquid gasket to

the shaded areas.
8.
When installing the cylinder head cover, hold the

head cover gasket in the groove by placing your fin-

gers on the camshaft contacting surfaces (top of the

semicircles).

Once the cylinder head cover is on the cylinder head,

slide the cover slightly back and forth to seat the

head cover gasket.

NOTE:

Before installing the cylinder head cover, clean

the cylinder head contacting surfaces with a

shop towel.

Do not touch the parts where liquid gasket was

applied.

Replace the washer when damaged or deterio-

rated.

8.7 Ibf-ft).

NOTE: After assembly, wait at least 30 minutes

before filling the engine with oil.ProCarManuals.com
